2 SICAM short-circuit indicators for cable and overhead line networks: Greater reliability, higher efficiency, lower costs For modern distribution networks to operate efficiently, faults must be quickly detected, packed in messages, and made available for further processing. With its SICAM short-circuit and ground-fault detection devices, Siemens now offers devices for recording and reporting faults in medium-voltage power systems. Prevent critical network situations and seamlessly monitor the status of your distribution network. SICAM short-circuit indicators help you reduce downtimes and optimize network quality. Efficiently increase the availability of your distribution network and benefit from the continuous improvement of your power supply. Highlights at a glance Fast fault location Improved efficiency Flexible use High availability Easy installation and commissioning No maintenance 2

SICAM FCM & SICAM FCG 1 / 2 / 3 Detect short-circuits and ground faults in mediumvoltage overhead line networks with SICAM FSI (Fault Sensor Indicator). The SICAM Fault Passage Indicator (FPI) is used to detect and report phase and ground faults in mediumvoltage cable networks. As a short-circuit and groundfault indicator with direction indication, SICAM FCM offers additional, precise measured values for monitoring the load of distribution networks. With SICAM FCG (Fault Collector Gateway), you can transfer all reported faults to a control center via GPRS or to a service team via SMS. Our cloud solution also allows you to work independently of a control center.

4 Short-circuit indicators for cable networks SICAM FCM and low-power sensors: A finger on the pulse of your distribution network Everything under control Do you want to improve the quality of your network? Then take advantage of a complete portfolio of products for network monitoring, power quality recording, fault recording, phasor measurement, and system software applications. SICAM FCM (Feeder Condition Monitor) is a short-circuit and ground-fault indicator with direction indication that uses protection algorithms and lowpower sensor technology according to IEC Alternatively, SICAM FCM can also be connected to a capacitive voltage tap to allow cost-effective directional fault detection in the cable network. Another possibility is the provision of up-to-date measured values via the integrated Modbus RTU interface, which permits you to make an accurate assessment of your distribution system. SICAM FCM can be used with all medium- voltage switchgear types in grounded, isolated, and resonantgrounded systems. Take advantage of high measuring accuracy and use SICAM FCM for investment planning in your distribution network. 4

8 Short-circuit indicators for cable networks SICAM FPI: The guardian of underground cable networks Economical groundfault recording Save time and money thanks to reduced downtimes: Rely on SICAM FPI (Fault Passage Indicator) the simple, economical solution for efficiently operating modern distribution networks. SICAM FPI reliably detects and reports ground and phase faults in radial and open ring cable networks. The threshold values of the permissible currents can be set at the four current sensors (L1, L2, L3, and E). In the event of a fault, the sensors send an optical signal to SICAM FPI via a fiber-optic cable fail-safe and isolated. The LEDs on SICAM FPI permit local indication. Using the binary contacts, they can forward fault messages to connected remote terminal units. Take advantage of these benefits Reduced fault-related costs and increased availability thanks to the fast detection of phase and ground faults in MV cable networks. Minimal operating costs with a maintenancefree, self-sufficient system that reliably operates with the aid of the back-up battery in SICAM FSI even if the main supply is tripped. Economical installation and a long service life guaranteed by easy-to-retrofit, IP67-compliant sensors with an interference-immune fiber-optic connection to SICAM FPI. 8

11 Short-circuit indicators for overhead line networks SICAM FCG: Reliable transmission of messages Direct connection to a control center: Messages are sent to a control center using a standardized telecontrol protocol. 2. Fault message in the cloud Messages are sent directly to maintenance teams, without the need for a control center. SICAM FCG (Fault Collector Gateway) establishes the connection to a control center via GPRS and sends messages using the standardized telecontrol protocol IEC To locate a fault more quickly, SICAM FCG can also send an SMS directly to the cell phone of a service technician. An alternative is the cloud solution : Using the XMPP protocol, fault messages and locations are visualized in the FLiC application on a smartphone. Maintenance teams are immediately informed without control centers, without complex IT hardware, and incredibly economically.
